I have taken to the dealership and they said, it's the transmission so I took it to a transmission shop and they said, no problem with the transmission so I took it to auto electric shop and they said, "there's nothing wrong with car" but I have still have the same problem.

I own a Lincoln Ls V8 with 55,000 miles. When I shift into reverse it creates a harsh sound, like the transmission is going to fall out. My "check transmission" light came on will be taking it to the dealership. I have been researching transmission problems on Ls and seems to be extremely common manufacturing problem. Something must be done!

In Nov 2008, while driving on a very busy street, I noticed the vehicle shifting very hard and at times causing a harsh jerk. As I attempted to make a left turn on a very busy intersection to return the vehicle home, the vehicle lost all power and the error message "etc engine failsafe mode" displayed on the screen. Thankfully the car slowly coasted across the 3-lane intersection without causing an accident. I had the vehicle towed to the Lincoln dealership and they stated that the throttle body need to be replaced. The throttle body was replaced ($761) only to have the same issue happen 2 months later in Jan 2009. When I turned the ignition on to start the vehicle the engine gave off a vehicle loud noise, the vehicle immediately lost power, and the "etc engine failsafe mode" error message was displayed again. Took the vehicle back to the same Lincoln dealership and this time they stated that the solenoid body in the transmission needs to be replaced for $1150. Upon asking why would I get the some error message and the problem is something totally different, the service advisor stated that the error message displayed was a "false code".

First it started out in July 2007, ac wasn't blowing like it should be replaced control heads. Then my trac control light came on and park brake light was on checked and advised replaced speed sensor. Then check engine light came on found upstream bank 2 02 sensor reading out of spec. Replaced 02 sensor and clear codes. That cost me$1285.51. Which I replaced sensor, spark plugs, coil then in Jan 2008 my transmission shift hard into reverse checked and advised found faults in solenoid, valve body, trans filter, repaired clear codes, ok. Replaced drive belt and pulley. That bill was $1318.72. Well then in 08/2008 same thing transmission shifts rough concern cylinder misfire. Check engine light back on. Thank god had a recall from Ford on that. Found contamination in both sides replaced affected coils, plugs, and cover which they only replaced 4 of the 8 coils. That would have been $593.18. Then on 08/2008 coolant leak just 3 days after getting it out of the shop had to replace leaking thermostat connector. Haven't had any problems running hot until they worked on it 08/11/2008. The power window was inoperative. The dealer replaced the regulator/motor. Updated 10/22/08.
